Based on a semi-global linearization a convergence theory for the implicit Runge-Kutta methods Radau Ia, IIa and Gauss is derived (including a proof for the solvability of the algebraic equations). ... Witryna21 paź 2011 · The work of Runge was extended by (Heun 1900), who completed a discussion of order 3 methods and pointed the way to order 4, and by (Kutta 1901) who gave a complete classification of order 4 methods. The most well-known method, due to Runge, has order 4 and is defined by the tableau. 0. 1/2. 1/2. how to set where scans are saved
